You forgot to return from test() and add its function prototype at the top, and add stdio.h

I know that about the setUp and tearDown. Didn't know about the testWatcher though. Thanks :)

setUp and tearDown should be optional too, but are probably useful for more compilcated test scripts.

Alright, but that was just an arbitrary number I put in so that it wouldn't time out. The thing is, no number in the actual test cases was that high.

I think the author somehow screwed with the Hash class to make it unusable for the solution. :/ as in, if you try to use this code for the solution it will just fail, period.

Using a hash will break in certain cases. Try reading about loop detection on wikipedia or stackoverflow for alternative strategies.

Not a general solution; will fail after 125!

just click the compare button next to any of the other solutions.
